Carbonaceous materials for the production of aluminium — Green coke — Determination of volatile matt...
Cancels and replaces the first edition (1988). Specifies a method for the determination, by gravimetric analysis, of the volatile matter in green coke used in the production of aluminium. Applicable to green cokes having volatile matter contents greater than 1 % (m/m).
Soil quality — Determination of total nitrogen — Modified Kjeldahl method
Specifies a method for the determination of the total nitrogen (ammonium-N, nitrate-N, nitrite-N and organic N) content of a soil. Nitrogen in N-N-linkages, N-O-linkages and some heterocyclics (especially pyridine) is only partially determined. Applicable to all types of soils.
Soil quality — Determination of organic and total carbon after dry combustion (elementary analysis)
Specifies a method for the determination of the total carbon content in soil after dry combustion. The organic carbon content is calculated from this content after correcting for carbonates present in the sample. If carbonates are removed beforehand, the organic carbon content is measured directly. Applicable to all types of air-dried soil samples.
